Airtac MARF Stainless Steel Mini Air Cylinder MARF20X130S
The AirTAC Airtac MARF Stainless Steel Mini Air Cylinder MARF20X130S is a genuine double acting + cushion (front mount) standard round-body mini air cylinder with a Ø20mm bore and 130mm stroke, 1/8" air ports and a stainless-steel barrel with a hard-chrome-plated rod for reliable, mildly corrosion-resistant service. A variable air cushion at both ends lets you tune end-of-stroke deceleration on site.

About the Airtac MARF Stainless Steel Mini Air Cylinder MARF20X130S
Built around a flange that is part of the front cover itself, the MARF20X130S is a double-acting 20 mm mini cylinder with 130 mm of stroke and a variable cushion you can trim at both ends. It produces 157.0 N on extension and 131.9 N on retraction at 0.5 MPa, rising to 219.8 N and 184.7 N at 0.7 MPa.
For sizing, treat about 94 N as the practical push at 0.5 MPa; that corresponds to lifting roughly 8 kg vertically with a 2:1 safety factor. The riveted stainless tube and hard-chrome plated rod resist corrosion in humid or outdoor plants, and the two-way piston seal traps grease so lubrication intervals stretch. Operating window: 0.15-1.0 MPa (22-145 psi), 30-800 mm/s.

Specifications follow the official AirTAC MA-series datasheet. Barrel: stainless-steel tube (round-body, riveted rolling-packed construction); piston rod: carbon steel with 20µm hard-chrome plating; covers: aluminium alloy. Thread options: PT (blank) / G / NPT. Every MA-series cylinder ships with a built-in magnet for CMSG / DMSG / EMSG position sensors.
Theoretical Output Force (Ø20mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 157 N | 132 N |
| 0.7 MPa | 220 N | 185 N |
| Max (@1.0 MPa) | 32 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac MARF Stainless Steel Mini Air Cylinder MARF20X130S Is Used
Label-head positioning on a packaging line
Sets a print-and-apply label head down onto passing boxes; the 130 mm stroke reaches across the conveyor edge and the cushion prevents head slam.
Scrap pusher beside a small bandsaw
Sweeps off-cuts into a catch chute after each cut; front-flange bolting keeps the cylinder square to the chute mouth without extra brackets.
Sample tray indexing in a lab analyser
Advances sample trays one position in a compact benchtop analyser; about 8 kg of vertical-lift capacity covers the loaded tray weight easily.
Is the Airtac MARF Stainless Steel Mini Air Cylinder MARF20X130S the Right Cylinder?
If 157 N at 0.5 MPa falls short, the next bore up, 25 mm, offers 245.3 N and the 32 mm bore reaches 402.2 N in the same family. This cylinder will not hold a load when air pressure drops; the cushion only softens the last few millimetres of travel, so fit a rod lock for secure holding. The integral front-flange face mates directly to a machine plate and the magnet works with CMSG, DMSG or EMSG switches.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) is standard for sensors
- ✓ Back cover (CA/U/CM) & mount (FA/LB/SDB)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Do not dismantle the riveted front/back covers.
- check On first run, back off the cushion screws and release gradually.
- check Installation by qualified personnel per AirTAC docs.
Airtac MARF Stainless Steel Mini Air Cylinder MARF20X130S FAQ
Push is 157.0 N and pull 131.9 N at 0.5 MPa; at 0.7 MPa the numbers are 219.8 N and 184.7 N, with a theoretical maximum of 32.0 kgf at 1.0 MPa. Supply 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-800 mm/s, air filtered to 40 um.
The rolled stainless-steel tube shrugs off moisture, mild chemicals and washdown splash that would rust a painted mini cylinder. Combined with the hard-chrome plated 8 mm rod, it stays smooth and sealed in damp food or outdoor locations. The magnet inside is standard and pairs with CMSG, DMSG or EMSG switches.
